I think it lacked some excitement because everyone knew Tana was getting his win back, but I really enjoyed the match and that was largely due to Ishii's on-point comebacks (that headbutt) and Tanahashi's structuring of the match.
Incidentally, the move he dunked Ishii on his head with before the High Fly Flow was the Twelve Six, which he rarely uses these days. I can't actually remember the last time he used it - anywho, during the match I was thinking "wow, Tanahashi's sure hitting a hell of a lot of slingblades" and then, lo and behold, he busts out not only the Twelve Six, but also the slingblade into a dragon suplex spot he hasn't much used recently either. Both big head drop moves that played on the repeated slingblades.
